But does OPSO’s cheaper cable actually work? Absolutely, in our testing there were no differences in charging between Apple’s charger and OPSO’s in terms of charging time or heating (both get warm). OPSO advertises as Apple MFi Certified which means it is part of Apple’s official Made for iPhone/iPad/Apple Watch program and meets Apple’s performance standards.

A few things to consider however. First, OPSO’s charger is white plastic like the versions included by Apple in the cheaper Apple Watch models. Apple’s standalone chargers are stainless steel like the ones bundled with higher end Apple Watch models. There’s no performance difference, but the visual difference is there.
